The ability of the Anterior Cruciate Ligament (ACL) to dissipate energy during cyclic loading conditions is crucial for understanding ACL failure. This study employs a novel mechanical test fixture for both shorter duration Digital Image Correlation (DIC) and longer duration Repeated Cycle-Recovery (RCR) ex-vivo experiments. The fixture ensured effective clamping and precise alignment of the Anterior Medial Bone-Ligament-Bone (AM BLB) samples while preserving the integrity and camera view of the region directly above the entheses. Results from the DIC and RCR experiments provide compelling evidence of localized hysteresis and evolving energy dissipation characteristics. The RCR experiments indicate a reduction in the energy absorption capabilities of the AM BLB with progressive cyclic loading, evident by a decrease in normalized hysteresis and diminished viscoelasticity over time. Furthermore, DIC experiments revealed strain concentrations in areas prone to acute ACL injuries. These findings underscore the importance of considering cyclic loading and localized strain behaviors in ACL failure mechanisms and may inform strategies for injury prevention and rehabilitation. © 2025, The Authors.

Increasing evidence is showing that per- and polyfluoroalkyl substance (PFAS) replacing compounds are not as safe as they were assumed. This study investigated the plant uptake of two most prevalent PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic (PFOS) and their replacing compounds, hexafluoropropylene oxide dimer acid (HFPO-DA or GenX) and 6:2 chlorinated polyfluoroalkyl ether sulfonates (Cl-PFESAs) (6:2 Cl-PFAES) by hydroponically grown lettuce in the presence of different nitrogen fertilizers including ammonium sulfate ((NH4)2SO4), potassium nitrate (KNO3), and urea in a growth chamber. Interestingly, (NH4)2SO4 significantly increased GenX uptake in lettuce shoots by ∼108% and KNO3 increased the uptake of PFOS and 6:2 Cl-PFAES by 267% and 395%, respectively, suggesting that the nitrogen fertilizer type has a marked impact on the plant uptake of PFAS and that this impact was PFAS-dependent. Our results also showed that (NH4)2SO4 generally resulted in higher PFAS root to shoot transfer than the other two types of nitrogen fertilizers. Metabolomic analysis revealed that amino acids, nucleotides, and antioxidants are the major metabolites that were either significantly increased or decreased in the lettuce shoots. These results showed that nitrogen fertilization management can have a significant impact on PFAS plant uptake and transport, and the impact depends on the types of nitrogen fertilizer and PFAS compounds. © 2025 The Authors.

The emerging field of porous piezoelectric strain sensors attracted a wide range of applications in healthcare monitoring, wearable electronics, and other dynamic applications due to their durability, high sensitivity, and real-time monitoring. This study presents the development of porous poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/copper oxide (CuO) nanocomposite membranes for piezoelectric strain sensing. The morphology and the dispersion of CuO nanoparticles and nanofibers in PVDF piezoelectric films with different nano-CuO contents are studied by X-ray diffraction, Fourier transform infrared spectrum, scanning electron microscopy and dielectric studies. The PVDF-HFP acts as a scaffold, allowing ions to flow within the porous percolated channels, resulting in a highly robust membrane with desired dielectric properties. The DMA studies enhanced the strain sensing performance of the 3.5 and 7 wt.% CuO nanofibers loaded with PVDF-HFP membranes compared with the 3.5 and 7 wt.% CuO nanoparticles and pristine membranes. The dielectric properties of the composites also showed high storage values for the CuO/PVDF-HFP samples compared to the pristine polymer. Moreover, the surface water contact angles of the membranes have slightly increased after loading the nanomaterial into the PVDF-HFP matrix, which strongly influenced the surface energies, indicating hydrophobicity. The current study, thus, demonstrates the piezoelectric strain sensing devices made from PVDF-HFP/CuO nanofibers for humid atmospheres. © The Author(s) 2025.

Thermal comfort is essential for maintaining physiological well-being, with textile materials traditionally serving as the primary medium for regulating heat exchange between the body and its environment. However, conventional textiles often fall short of maintaining optimal thermal balance. So, there is an increasing demand for advanced thermoregulation systems that can effectively reduce heat loss and enhance warmth, ensuring consistent comfort. Recent research has highlighted the promise of advanced functional materials, especially graphene and its composites, for modifying textiles to improve thermal properties. This article comprehensively reviews recent advancements in graphene-functionalized textile composites, focusing on their applications in wearable Joule heaters designed for personalized thermal comfort or thermal therapy. Various graphene-functionalized textile composites are reviewed from the perspectives of material properties, processing strategies and device fabrication methods. Key challenges and future opportunities are summarized for graphene-functionalized textile-based Joule heaters as innovative solutions in wearable thermal regulation.

Synergistic Effect of Natural Vitamin E and Antioxidant 1010 Combinations on the Stabilization of Polypropylene

With increasing safety concerns of synthetic antioxidants, completely or partially substituting these compounds with natural ones is a potentially feasible approach. However, the stabilization effectiveness of natural antioxidants alone was usually limited. In this work, it was found that the combination of vitamin E (VE), a natural antioxidant, with the synthetic hindered phenol antioxidant 1010 significantly enhanced the thermal-oxidative stability of polypropylene (PP). The samples with 0.2% VE and 1010 alone had an oxidation induction time (OIT) of 6.3 and 20.5 min, respectively, while samples with the same total addition amount (0.1% antioxidant 1010 and 0.1% VE) markedly prolonged the OIT to 55.5 min. The results of melt flow rate and yellowing index alterations following processing-induced aging and carbonyl index changes after oven aging indicated that the combination of VE and antioxidant 1010 exhibited a pronounced synergistic effect. Mechanistic research suggested that the enhanced antioxidant effect was attributable to the synergistic regeneration of VE by antioxidant 1010. This mechanism was further demonstrated by the thermal-oxidative stability of a combination of VE and another 2,6-di-tert-butyl-hindered phenol, antioxidant 1076. Our findings provided an important foundation for developing efficient and safe polymer products by reducing the use of synthetic antioxidants. © 2025 Wiley Periodicals LLC.

Interfacial polymerization has been an industrial standard for preparing desalination membranes. Extending the same concept to molecular separation of organic solvents would be a key enabler for the decarbonization of the chemical and petrochemical industries through energy-efficient crude or biocrude oil fractionation. Here, we report a molecular engineering approach based on acid-catalyzed interfacial polymerization for efficient hydrocarbon separation. The design strategies include (i) changing the linkage from amide to imine and (ii) subsequent introduction of shape-persistent units such as triptycene and spirobifluorene. The prepared polyimine membranes exhibit ultrahigh microporosity and enhanced swelling and plasticization resistance compared with conventional polyamide counterparts. These membranes, which feature fast and selective transport of hydrocarbons, including multicomponent and industrially relevant mixtures, outperform commercial and state-of-the-art benchmark membranes.
